GUDGEON FOR WINDQW SHADE ROLLERS.

SPECIFICATION forming part of Letters Patent No. 298,611, dated May 13, 1884:.

Application filed January Ell, 1884. (No model.)

To all whom it may concern Be it known that I, JosErH MUNGER, of \Vaterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Gudgeons for VVindow-Shade Rollers; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and whichsaid drawings eonstitute part of this specification, and represent, in-

Figurel, aperspeetive View; Fig. 2, a cen tral section; Fig. 3, a central section of the cup detached; Fig. 4, the flanged gndgeon detached; Fig. 5, the gudgeons attached to the roller; Figs. and 7, modifications.

This invention relates to an improvement in gudgeons for window-shade rollers, and particularly to that class which are secured to the end of the roller, in contradistinction to those which are driven into ahole bored into the end of the roller. In the more general construction of this particular class of gudgeons the gudgeon has been cast as a projection from a plate fitted to be attached to the end of the roller, and this attachment has been made in some cases by holes through the plate, through which nails or screws are driven into the end of the roller. In other cases a ring has been applied to the end of the roller, having a flange projecting inward over the gudgeon -p1ate, this flanged ring serving to hold the gudgeonplate to the roller; but in either of these con structions it is necessary that the end of the roller shall be cut in a perfect plane at right angles to the face of the roller, in order that the gudgeon may project in a direct axial line therefrom. Any deviation from such a rightangular plane will turn the gudgeon out of its axial line and cause it to work imperfectly. Again, such construction of the gudgeon-plate necessitates the cutting of the roller to an exact length, and if it be cut shorter than such exact length then there is no means of adjustment to bring the gudgeon into its proper relative position to the bracket, and the roller is useless for that particular window.

The object of my invention is the construction of a gudgeon in which the perfect axial and concentric position shall be insured irrespective of the plane on which the end of the roller is cut, and also one which will allow some considerable variation in the length of the roller without interference with the proper working of the gudgeon, and it consists in a sheet-metal cup of a diameter corresponding substantially to the diameter of the roller, and so as to be set on over the end of the roller, the said cup having the gudgeon arranged and secured concentrically in its closed end, as more fully hereinafter described.

A is the cup-shaped body, which is struck from sheet metal, the internal diameter corresponding substantially to the diameter of the roller, and so as to closely fit when placed over its end. At the center is a perforatiomu, corresponding to the diameter of the gudgeon, and around this openingthe bottom of the cup is struck outward, so as to form a recess, 1) upon the inside, as seen in Fig. 3.

d is the gudgeon, around the inner end of which a flange, e, is formed by upsetting the metal or otherwise, in diameter and thickness somewhat less than that of the recess bin the bottom of the cup. This gudgeon is passed through the hole a from the inside outward, the flange 6 set into the recess b, as seen in Fig. 2, and there soldered or otherwise perinanently fixed in its position. The gudgeon is made from hard metal, and preferablyfrom wire, upset in the usual manner of making headed rivets. This completes the gudgeon. It is attached by'placing the cup open end onto the roller, as seen in Fig. 5. The sides of the cup locate the gudgeon with relation to the roller, and so that the face of the cup will stand at right angles to the axis of the roller irrespective of the shape of the end of the roller-that is, it may be cut at an angle, as seen in Fig. 5yet the face from which the godgeon projects is certain to be at right angles to the axis of the roll and the gudgeon to be concentric and in direct axial line, and should the roller be out too short, then the cup will be set onto the roller only so far as to bring the face of the cup and the gudgeou into the proper relative position.

Instead of making the gudgeon from a headed rivet and introducing it through the hole a in the end of the cup, so as to bring the head upon the inside of the cup, the gudgeon may be made with a projection, f, upon the opposite side of the flange, as seen in Fig. 6, and that projection introduced through a central hole in the cup from the outside, as seen in Fig. 7 and there riveted down upon the inner side of the cup; but I prefer the first-described method of attachment.

I claim- 4 l 1. The cup A, constructed with a central hole, a, in its bottom, combined with the flanged gudgeon cl, secured to said cup through said central hole, substantially as described.

7 2. The cup A, constructed with the central I 5 recess, 5, upon the inner side of its bottom, and with a central hole, a, therein, combined with the flanged gudgeon d,introduced through the said central hole, a, to bring its flange into said recess, and there secured, substantially as 20 M.
